Abstract
Solar cells have been fabricated from unconventional silicon materials supplied in the Large Area Sheet Task of the Low Cost Solar Array Project. The cells were constructed using methods intended to optimize the efficiency, as well as by a standard method intended to act as a baseline procedure. Following fabrication, all cells have been measured on the Spectrolab Solar Simulator at Air Mass Zero and 28/sup 0/C. Conversion efficiencies are based upon total device area. Maximum conversion efficiency obtained for Kayex continuous CZ material has been 12.4% (optimized), for Crystal Systems HEM material 11.2% (optimized), for Mobil Tyco EFG (RH) 8.4% (baseline) and EFG (RF) 9.8% (baseline), for Westinghouse Web material 12.0% (optimized), for Motorola RTR 7.2% (baseline), and for Wacker Silso 10.6% (baseline). All of these materials are from Phase I of the Contract. Phase II of the contract has started with Mobil-Tyco EFG (RH) material. Following fabrication by the baseline method this material, as well as the others in the program, will be fabricated using low-cost processing methods.
